Compaq TRU64 AA-RNG2A-TE - Manual (Page 92)

8 Sets the if_version member of the ifnet data structure for this
device to the string 3Com EtherLink III.
6.7 Setting the Baud Rate
The following code shows how the el_attach( ) routine sets the baud rate:
ifp->if_baudrate = ETHER_BANDWIDTH_10MB; 1
1 Sets the if_baudrate member of the ifnet data structure for this
device to the constant ETHER_BANDWIDTH_10MB. The if_baudrate
member specifies the line speed.
You can use the following media-specific constants:
ETHER_BANDWIDTH_10MB
Ethernet line speed is 10 megabits per second.
The if_ether.h file defines the ETHER_BAND-
WIDTH_10MB
constant.
ETHER_BANDWIDTH_100MB
Fast Ethernet line speed is 100 megabits per second.
The if_ether.h file defines the ETHER_BAND-
WIDTH_100MB
constant.
FDDI_BANDWIDTH_100MB
FDDI line speed is 100 megabits per second. The if_fddi.h
file defines the FDDI_BANDWIDTH_100MB constant.
TRN_BANDWIDTH_4MB
Token Ring line speed is 4 megabits per second. The if_trn.h
file defines the TRN_BANDWIDTH_4MB constant.
TRN_BANDWIDTH_16MB
Token Ring line speed is 16 megabits per second. The
if_trn.h
file defines the TRN_BANDWIDTH_16MB constant.
6.8 Attaching to the Packet Filter and the Network Layer
The following code shows how the el_attach( ) routine attaches to the
packet filter and the network layer:
attachpfilter(&(sc->is_ed)); 1
if_attach(ifp); 2
el_configured ++; 3
1 Calls the attachpfilter( ) routine to inform the packet filter driver
about this network driver. The attachpfilter( ) routine is passed
a pointer to the ether_driver data structure for this network device
driver.
